Mini-invasive treatment of median arcuate ligament syndrome, a case report

Abstract

Introduction: Median arcuate ligament syndrome (MALS), also known as Dunbar syndrome or celiac artery compression syndrome, is a rare disorder due to external compression of the celiac trunk (CT) by the median arcuate ligament (MAL). The diagnosis is difficult and often one of exclusion, because of its nonspecific symptoms that overlap with other forms of chronic intestinal ischemia. Laparoscopic approach is considered to be an optimal therapeutic option. Material and Surgical Techniques: We describe the case of a 40-year-old woman who presented with a 4 years-long clinical history of postprandial abdominal pain, occasional vomiting and severe weight loss in the last year. An abdominal CT scan demonstrated an external compression of the CT and the patient underwent laparoscopic decompression by division of the MAL. Postoperative course was uneventful and the patient was discharged on the 5th postoperative day. Discussion: Despite being MALS a rare disease, it must be kept in the differential diagnosis of abdominal pain. Diagnosis is difficult and often requires 2nd level investigations. Laparoscopy can be useful both as a diagnostic and curative approach. The laparoscopic division of the MAL is a feasible and safe procedure, leading to an improved quality of life
